1 – Parameters
1.1 – n
    Specifies the number of occurrences of the array. This number is
    greater than zero.
1.2 – index-name
Specifies the field element that functions as an index.
2 – Description
    The OCCURS field property declares one or more fixed-length,
    one-dimensional arrays.
    The n value represents the upper bound of the array; the lower
    bound is always 1. Use the ARRAY field property to specify a
    lower bound other than 1.
3 – Examples
    1.CDO>  DEFINE FIELD MULTIPLE
      cont>   OCCURS 3 TIMES
      cont>   DATATYPE IS SIGNED LONGWORD.
      In this example, the OCCURS field property in the DEFINE FIELD
      command creates the MULTIPLE field element, which occurs 3
      times.
    2.CDO>  CHANGE FIELD MULTIPLE
      cont>   NOOCCURS.
      In this example, the NOOCCURS keyword removes the OCCURS
      property from the MULTIPLE field element.
